A Review of PalmOnes Zire 72 and 31
by Wei-Meng Lee01/17/2005
Recently, palmOne has been churning out new models of its popular handhelds. They have three main product ranges:
- Zire handhelds: Targeted at the widest range of users, with three different models: the Zire 21, Zire 31, and Zire 72. The Zire 21 is of entry-level quality and sports a monochrome display. The Zire 31 and Zire 72 are more geared towards users who want a color screen and expandability. The Zire 72 also includes a built-in camera.
- Tungsten handhelds: Targeted more at business users, the Tungsten series has three models: the Tungsten E, Tungsten T3, and Tungsten C. The Tungsten E is the entry-level model; the Tungsten T3 comes with Bluetooth capability, and the Tungsten C has Wi-Fi built-in and includes a keyboard.
- Treo Smartphone: This is the Smartphone from palmOne that also comes with a built-in keyboard.
I was interested to see how the latest models stacked up against each other and selected two particular models to evaluate in this article. I have gone for two Zire models, the 31 and 72, since they are priced for two different groups of users. The Zire 31 costs $149, and is clearly targeted at first-time users of PDAs who would nevertheless like to have a color screen.
The Zire 72 is priced at $299, twice as much as the Zire 31. It has Bluetooth built in, as well as a 1.2MB camera. This should appeal to more sophisticated users who want to take pictures with their handhelds and will probably use them to get connected through their Bluetooth-enabled cellular phones.
Zire 72
The Zire 72 is an upgraded model of the Zire 71, with an improved camera, faster processor, and a larger memory.
The Zire 72 uses the newer 312MHz Intel PXA270 processor and runs PalmOS 5.2.8. It has a 16-bit, 320 by 320 high-resolution transflective TFT color display that supports 65,000 colors. In terms of memory, it has 8MB of masked ROM and 32MB of SDRAM, 24MB of which is accessible by the user.
Figure 1. The Zire 72
The Zire 72 has a built-in 1.2MB camera with 2x digital zoom, capable of a maximum resolution of 1280 by 960. It can also capture video at 320 by 240 resolution. Figure 2 shows the camera located at the back of the Zire 72. The wire mesh conceals the speaker.

The camera software in the Zire 72 supports different special effects: Normal, Sepia, Black and White, and Blue. To test the camera, I used it to take a snapshot of my room under normal lighting conditions (the device has no flash). Figures 3 to 6 show four photos taken with the camera at 1280 by 960 resolution with different special effects.

The image quality is acceptable, but definitely is in no way comparable to images taken by a digital camera.

On the networking side, the Zire 72 comes with built-in Bluetooth support, which makes it easy for you to pair up with a Bluetooth-enabled cellular phone for GPRS Internet access and sending SMS/email messages from your PDA. It comes with a user-friendly utility to set up Bluetooth devices, shown in Figure 7. I find the Bluetooth capability useful when I need to send photos taken on the Zire 72 to my desktop. While the Zire 72 comes with Bluetooth, Wi-Fi is not a standard item (but can be added by purchasing a wireless SD card).
In terms of expansion options, the Zire 72 supports MMC (Multi-Media Card), SD and SDIO (see Figure 8).

To test the responsiveness of video playback, I copied a 22MB Windows Media file to the Zire 72 (see Figure 9). The playback was smooth and the sound quality good.

The bundled RealOne Player (see Figure 10) included with the Zire 72 doubles as an MP3 player. Just buy an SD memory card, and you have a portable music player with great sound quality.

The Zire 72 comes with the following software:
- palmOne Quick Install (Windows only)
- palmOne Media Desktop Extension (Windows only)
- Synchronization with Microsoft Outlook (Windows only)
- NotePad, VoiceMemo, and Expense (Expense is Windows only)
- Mac users get a Send to Handheld droplet that allows for the easy installation of photos, videos, and MP3s using the Hotsync process.
- Software Essentials CD
- Documents To Go Standard Edition
- palmOne VersaMail
- palmOne Web Pro
- palmOne Messages (SMS/MMS)
- Acrobat Reader
- Solitaire
- Palm Reader
- powerOne Personal Calculator
- Java Virtual Machine (Internet download and valid email address required, Windows only)
- Audible Player for palmOne handhelds (Windows only; requires a software download from the Internet to your computer and a separate subscription to purchase audio books from Audible)
- Bluetooth, Calculator, Calendar, Camera
- Card Info, Contacts, Dialer, Expense, Memos
- Media, Note Pad, Prefs, Quick Tour, Real One
- Mobile Player, Tasks, Voice Memo, World Clock
Zire 31
When I next reviewed the Zire 31 ($149), my first reaction was influenced by the quality of the screen (see Figure 11), which was less than ideal compared to the better screen of the Zire 72. In contrast to the Zire 72, the Zire 31's screen is a STN (Super Twisted Nematic) display with resolution of 160 by 160. The 8-bit display supports 4,000 colors. While the color screen is acceptable to me, it will not allow you to play games, which need a higher resolution screen.
Figure 11. The Zire 31
The Zire 31 also runs Palm OS 5.2.8 and has 16MB of RAM (of which 14MB is accessible). It has a speedy 200MHz Intel ARM-based processor and has no wireless connectivity built in, except for the infrared port. It does, however, have an SDIO expansion slot (see Figure 12).
Figure 12. The expansion slot of the Zire 31
Note that the Zire 31 has only two buttons, compared to four on the Zire 72 (see Figure 13). However, both the Zire 31 and 72 have a five-way directional pad, which is useful to gamers.

Zire 72 (right)
The Zire 31 comes with the following applications:
- Contacts
- Calendar
- World Clock
- Memos
- Tasks
- Calculator
- Expense1
- Prefs
- Note Pad
- RealOne™ Mobile Player3
- palmOne™ Photos
- Audible
- Handmark™ Splash Money® and Mobile DB™
- powerOne™ Calculator
- Palm™ Reader
- AddIt
- Solitaire
Like the Zire 72, the Zire 31 includes the RealOne player, allowing you to play MP3s on your PDA.
Summary
Overall, my impression of the Zire 72 is good. The speedy Intel XScale processor makes the PDA responsive, and the Bluetooth setup utility makes setting up Bluetooth devices a breeze. However, the camera quality is only acceptable, but this is understandably so. The Zire 31's main disadvantage is its low-resolution screen. Long periods of usage will make you want to perform an organ transplant on the Zire 31.
Both the Zire 31 and 72 performed well as music players, but video is definitely out on the Zire 31. In terms of processing power, the Zire 31 performs reasonably well due to its fast Intel processor. Which one would I choose if I were to buy a Palm-OS-based PDA? I would definitely go for the Zire 72, but if all you want is a simple PDA to keep track of your contacts, the Zire 31 is a good choice.

Zire 31/72
2006-02-02 08:19:20 kb0sei [View]
I own a Zire 31 and I love it. I don't need the hires screen, but I do have theTCPMP video player. Comes in handy when I drive field trips for school, as does the GPS from iGolf.
The one thing I don't understand is why Palm has a SD wireless adapter that they say isn't compatible with the 31. Has anyone confirmed this? I am curious. I haven't found any peripherals to connect to the mini-USB port, either.

Zire 31 corrections
2005-06-30 19:37:38 kryptic [View]
I do not know where the author got his information on the Zire 31 but there is definatly a few errors. The Zire31 is more than capable of playing back videos of many different formats, Divx, Xvid, etc. The playback quality really depends on the size of it and sound, playing a 640x480 48 megabyte animation file at full speed(29-30fps)is handled quite well with the TCPMP player. How ever playing back a file like that with stereo sound is not handled very well.
Using a program like Virtual Dub, taking that 48 meg file and re-sizing to 320x240, 24 kBit/s 22,050 Hz mono sound, encoding bitrate at 768 kbps, in divx using its portable profile there are no problems playing it back with sound on the Zire31. As well as getting the file down to 5.16 MB.
So don't beleve all that you read, also I would be willing to bet you can get the SDIO wireless card from PalmOne to work on the Zire31's.

WiFi on my Zire 72
2005-02-03 06:03:18 trevz72 [View]
I am writing this on my Zire 72 while connected to the web with the WiFi card.
Yes, it was easy to set up and works like a charm. It works anywhere in my house (at least a 50 ft. radius) using my Apple Airport Extreme. I do want to mention, however, that it will drain a full battery in less than 30 minutes. So just keep that power cord handy. -
WiFi on my Zire 72
2005-02-21 11:14:53 jmitchell [View]
Thanks for you post about using WiFi on your Zire72.
Could you tell me which model/mfg you purchased and where.
I've heard conflicting reports and I want to buy something that someone's already using and know works.
Thanks,

Got one for my [non-techie] wife for Xmas.
She likes it a lot. Big move up from an
old Palm that she quit using because it
was clunky. The BlueTooth is nice for syncing
with her Mac G5 [got the bluetooth for wireless
keyboard and mouse], but is WAY too slow to
upload music or download photos.
Connectivity is good enough for what she wants
though, so likely won't get the Wi-Fi adapter.
Am thinking about the GPS nav system [uses
bluetooth to talk to receiver].

PalmOne Zire 72 with TomTom GPS
2005-03-27 15:53:59 furbyjinmd [View]
I now have my Zire 72 GPS up and running and am EXTREMELY happy with it. I now am impatiently waiting for TomTom to release the Apple version of their software so I can perform my own installs and updates. I regret I had to ask a friend with a PC to assist in getting me up and running.
Highly recommend this equipment. I've seen instances when I was receiving data from SEVEN satellites on this system. I now hope they will go to a nautical version as well since that is so much in demand in the area of the Chesapeake Bay. -

Zire 72 with GPS
2005-01-28 20:07:57 furbyjinmd [View]
Just wanted to let you know I have the GPS on the way--expected to arrive around February 1, 2005. I'm anxious to see how it works, but disturbed that I had so much difficulty locating it. Had to buy another Palm Zire 72 when I had one about a month old because that was the only way I could locate the GPS system for the Zire 72.

Wireless support
2005-01-19 05:34:04 GraemeW [View]
I'd love to hear from someone (including the reviewer) who has tried the Wifi card on the Zire 72. Does it work?
I did try networking over Bluetooth (using a Bluetooth dongle and bridging on my Win XP PC) with some success. The screen is definitely big enough to read some web pages comfortably and some sites such as Hotmail and Yahoo have special mobile pages, but Bluetooth is fairly slow and at least in my configuration the connection seemed to drop out regularly.
My experience with Bluetooth makes me want a WiFi card all the more, but I'm not about to pay more than $100 for one until at least one person has tried it and reports success.

It is a good "bargain" - the best Palm Os based PDA you can get for your money. The only annoyance is the bundled case. I'd recommend to buy the metal case for ~20$. This PDA made me truly happy. -

Instead of the metal case I would recommend the Active Case by BoxWave.
